This chapter provides an overview of mine tailings and mine tailings facilities. It illustrates why and how mine tailings are produced, and the complexity involved in the long-term storage and management of this waste product. The call for a global standard for mine tailings management is a response to recent catastrophic facility failures. Mining …
To be able to corroborate the environmental and economic benefits of future tailings-reprocessing flow sheets based on the know-how developed in WP1–3, WP4 develops a novel environmental assessment methodology that is …
Tailings management has long been a concern in mineral processing operations, and recently has been brought back to our attention after multiple facility failures. In this month's blog, we look at how switching from a reactive to a proactive approach to tailings management can provide more long term economic, social and safety benefits.
This study is focused on the froth flotation reprocessing of a copper mineral from flotation tailings. The effects of flotation parameters including pulp density, collector dosage, frother dosage ...
The pioneering Tailings Reprocessing Project at Golden Sunlight has the potential to generate tens of millions of dollars in tax revenue and benefits for Montana over the next decade, while removing a source of possible water pollution from the mine site.
Results indicate that reprocessing may save from 25 up to 930 kg CO 2 -eq per tonne of treated copper tailings. Potential environmental benefits depend on the …
Abstract This research aimed at recovering metals retained in the tailings from the flotation of copper (Cu) and cobalt (Co) ores conducted at the New …
The first case corresponds to the reprocessing of secondary copper from an abandoned tailings dam. The second case study analyses the extraction of copper and molybdenum through the reprocessing of an old tailing dam that is …
Reprocessing of old mine tailings can be both economic and environmentally friendly solution through recovering a substantial amount of copper, gold, and sulfur into concentrate, that can be utilized in smelting as a source of …
In addition to reprocessing mine tailings for economic value, there are environmental and humanitarian benefits associated with treating the tailings, removing various sulfur-bearing minerals and heavy metals, finding beneficial uses for other gangue minerals, and reducing the volume of tailings waste stored in dams.
Sul dic copper tailings in the EU were se-fi lected as a case study. We perform prospective life cycle assessments of future reprocessing scenarios by considering emerging resource recovery technologies, market supply demand forecasts, and energy system changes.
The re-processing of mine tailings to obtain critical raw materials (CRMs) could reduce the mining of new deposits as well as ensure the profitable us…
Sulfidic copper tailings in the EU were selected as a case study. We perform prospective life cycle assessments of future reprocessing scenarios by considering emerging resource recovery technologies, market supply & demand …
Copper production has increased throughout the twentieth century, and this trend has continued over the last twenty years. The demand for copper is expected to increase significantly by the year 2030. Owing to the high prices of this metal and the lack of deposits, part of the demand can be met by extraction from copper-bearing tailings.
Critical Metals in Copper Mine Tailings. We are pleased to announce the launch of our Regents' Research Grant project Reprocessing Copper Mine Tailings: Critical …
The value of copper and tungsten recovered during reprocessing could be used to offset the reprocessing costs. This study aims to investigate the potential for pyrrhotite recovery from the Cantung tailings using magnetic separation and flotation.
This study conducts a process-based life cycle assessment (LCA) study to investigate multiple reprocessing pathways of copper tailings to co-produce …
This article reviews the evolution of copper tailings management and governance in Chile, current practices, and changes that could be or may need to be made to improve practices in response to local environmental conditions and local tolerance for risk. The progress to date in developing a holistic tailings management strategy is …
Copper production has increased throughout the twentieth century, and this trend has continued over the last twenty years. The demand for copper is expected to …
Worldwide, an issue of copper production is the generation of mine waste with varying characteristics. This waste can pollute natural environments, and in particular, the heavy metal emissions of the tailings may pose long-term consequences. Currently, life cycle assessments of mine tailings are hampered by both limited data availability in the …
Codelco and Sibanye Stillwater are also reprocessing their tailings with high commodity grades to extract residual metals, including copper and platinum. And, in May 2023, Sibanye acquired New Century Resources whose innovative tailings recovery-based business model I covered in this Intelligent Miner article .
Tailings management within the circular economy in mining. In this chapter, the possibilities to manage the mine tailings with reduce, reprocessing, upcycle, downcycle and disposal strategies are discussed. In the subchapter 5.2, an inventory of the metal content of mine tailings in Finland is presented. 5.1. Reduce.
Results indicate that reprocessing may save from 25 up to 930 kg CO 2 -eq per tonne of treated copper tailings. Potential environmental benefits depend on the reprocessing routes, technology upscaling parameters, and quality of secondary products.
Reprocessing flowsheets for copper mine tailings in Chile were developed and costs and revenues of possible products from reprocessing were examined for a rough economic assessment.
A standard method of reprocessing involves dragging tailings from an existing dam back to the concentrator and using selected mineral processing solutions to liberate the valuable metals.
ntinued copper is expected twentieth increase significantly high prices of this metal and by to year 2030. Owing to the lack of deposits, of the demand can be met by per-bearing tailings. In the past, owing extraction from cop- level of technological development prices, materials comparable today have in copper content and lower to the costs ended up …
By reprocessing tailings, dewatering them and then storing them in a dry stack, mines can remove some of the economic, environmental and societal risks associated with tailings stored in slurry.
Different approaches to tailings valorization can be taken, such as reprocessing to extract metals and minerals, tailings as backfill material, tailings as construction material, energy recovery and carbon dioxide sequestration ( …
ntinued copper is expected twentieth increase significantly high prices of this metal and by to year 2030. Owing to the lack of deposits, of the demand can be met by per-bearing …
